| CHEMSEAL expansion joint sealant  EMSEAL, a manufacturer of preformed sealants and structural expansion joints, announced the development and release of its CHEMSEAL expansion joint sealant. CHEMSEAL is a chemical-resistant, precompressed, primary seal for expansion joints and construction joints where contact with chemicals and chemical dilutions is expected. CHEMSEAL is constructed of a resilient, clean handling, non-staining, microsphere-modified-acrylic-impregnated foam which remains flexible at low temperature and stable at high-temperature. This foam backing is factory pre-coated with a chemical-resistant polysulfide sealant which forms a watertight bellows at the side exposed to liquid and chemical contact. Installed into field-applied epoxy and finished with an injected sealant band of EMSEAL-supplied polysulfide liquid sealant, CHEMSEAL offers the benefit of non-invasive anchoring which allows for greater ease of installation.CHEMSEAL+5 is the first product release in an expanding line of CHEMSEAL products from EMSEAL. In prolonged submerged applications it has been successfully tested to continuously resist water pressure of up to 5-ft without product deflection or leakage. CHEMSEAL variations, engineered for applications involving head-pressures greater than 5-ft, are also available-consult EMSEAL. The ability of CHEMSEAL to work in submerged or intermittent-contact applications make it an ideal sealant system in new or retrofit construction in infrastructure applications including waste water treatment facilities, secondary containment, chlorinated water environments, pools, fountains and water parks. "CHEMSEAL's ability to form a seal while offering resistance to chemicals makes it an ideal solution in a broad number of industrial, infrastructure, public works and recreational applications," stated EMSEAL President and CEO, Lester Hensley. "By taking advantage of the chemical resistance of polysulfide liquid sealant while diminishing its weaknesses-namely tensile stresses in the body of the cured sealant as well as at the bondline-we have created a hybrid sealant that is the answer to many structural and other joint sealing challenges in projects today." write your comments about the article :: © 2009 Construction News :: home page |
